## Questions & Answers

**Q: one of my cats is going over my chain link fence.  Would this work with putting it at an angle with some small mesh? fencing on it to keep the cat in.**
A: Yes, we bought some for just that purpose. Both chicken wire and black, plastic deer fencing work. Deer fencing is easier to cut. I'd avoid mesh since birds may become entangled.  :-(  Cable ties help keep everything in place.  I painted ours black. You may have to brush off snow or falling leaves from time to time. And, keep shrubs short underneath. But ours cat containment system has worked for years. :-)

**Q: How far apart can you put these?**
A: We recommend placing each barb arm around 5 to 8 feet apart depending on the amount of tension you are looking for in the wire

**Q: The outside diameter of my top rail is exactly "4.25 inches. That's wrapping around the outside of the top bar. What am I doing wrong?**
A: I take you to mean the circumference (not diameter) of my top rail is 4,25 inches.  Pipe is measured by diameter and top rails for chain link fencing comes in two sizes: 1-3/8 inch and 1-5/8 inch  With a circumference of 4.25 inches, you have a 1-3/8 inch rail.  Is the the size you ordered? I see it comes in both sizes.

**Q: Can these support enough weight (when fully tightened) for a 8ft section of 2lb mass loaded vinyl? (about 85lbs including the cable and grommets)**
A: I can't guarantee that these will hold that much weight, even tightened. We have an updated clamp-on post extension that could very well hold the weight. Please see our other listings for the clamp on vertical or horizonal extensions.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy and heavy duty
*by H***N on March 6, 2023*

Just what I needed. I looked up company. Saw they specialized in fencing material and was not a cheap runoff. Very pleased, easy installation, heavy duty steal, exactly what I needed to keep my dog from getting out. Only negative thing is about seven arms of the 27 ordered were missing the screws or nuts. You can buy them at a hardware store and being that this is a good product. The screw issue seemed minor to me. I would and will buy more. You can use wire or a variety of fencing on these arms.

### ⭐⭐⭐⭐⭐ Cheap and fast way to keep them doggies in your yard
*by C***. on June 13, 2022*

My german shepherd/doberman mix is an escape artist, and this shut her down. Super fast install, just used a socket wrench and I put up 18 of these in 30 minutes. Very sturdy galvanized steel, so won't rust any time soon. I didn't want to use barbed wire which might hurt my pup, so used 14 gauge electric fence wire instead from the local hardware store. Woof!

### ⭐⭐⭐⭐⭐ Strong and sturdy  looks professional
*by V***E on October 19, 2023*

The media could not be loaded. We needed this for our fence that backs up to a green space. Our fence is 6’. My husband put the brackets on which was simple. We were impressed how sturdy they were. We strung the 12 gauge barbed wire starting on the lowest first. We stretched the wire across each bracket, hooking it in the slots and once we got to the end, we stretched each section and secured with a wire. We painted it with black spray paint and it disappeared! The fence looked very professionally done. We are very happy with it!
